Ranbir Kapoor may have started shooting for Abhinav Kashyap's 'Besharam' but he still has his previous project to complete. TOI has learnt that a crucial song sequence is still to be shot for Ayan Mukerji's 'Yeh Jawaani Hai Deewani'. Ranbir will be seen grooving to his uncle Randhir Kapoor's chartbuster from 'Jawani Deewani' after which Ayan's film is titled.

According to a source,the song to be shot in April 2013 would have a retro feel with Ranbir incorporating his uncle's steps from the 1972 musical. "But Ranbir and his director Ayaan Mukerji don't want it to be too retro either. R.D. Burman's original composition would remain intact. But the dance steps would be re-done completely," the source added.
